At the grand opening of Lamborghini Calabasas on Wednesday night, celebrities drove fast cars for a good cause as Heroes star Greg Grunberghosted the party, which featured DJs English Mafia, to benefit the Epilepsy Foundation. But male model extraordinaire Fabio (who has two Lamborghinis at home) was just happy to get out of a charity event without a scuffle. Earlier this month, at a different charity dinner, the long-haired hunk got into it with George Clooney and now he’s telling OK! his side of the story.

“I was doing a charity for the 11-99 Foundation, which benefits the widows and children of officers killed in the line of duty,” says Fabio of the infamous Nov. 2 dinner at Madeo. “I had dinner with six women and a photographer woman and we were just having fun, having dinner and taking pictures. All of a sudden one of the ladies said to me, ‘There is this gentleman a few tables behind you that keeps insulting me, keeps giving me the finger.’ She’s like, ‘This gentleman behind you called me a fat cow.’”

“So I turn and it was him,” Fabio says of Clooney. “He was drunk and thought people were taking pictures of him. So I went to the table and explained to him that we were having a charity dinner and I said, ‘You’re more than welcome to come to my table and see if there was a picture of you.’ I apologized and he started being rude so I put him in his place. After I put him in his place — you know I’m three times his size — he got a little scared. I went back to my table and as soon as I sit down he paid his bill, got up and he started insulting the girls. He called the women names. At that point I lost my temper. I went after him and he ran out of the restaurant.”

“He has no class,” Fabio tells OK!. “You have to be a low-class, scumbag to start calling a woman a name. If you’re a man, you should never. You should be a gentleman. These women were with me and as a man I defend them. He was lucky he ran out of the restaurant. He’s not even half a man.”
